1 Prerequisites

Before the classes I would like to ask you to follow the instructions mentioned below to prepare your device for the class work:

install R from the following link: https://cloud.r-project.org/
install RStudio from the following link: https://rstudio.com/products/rstudio/download/#download (FREE version, no need to pay!)
after the installation run the RStudio program, type 2+2, and press Enter.

If you see something like this, then you are well prepared for classes.

Go to the https://rstudio.cloud/ website and sign up there. This is optional, but it will be a backup version, if something will not work on your computer.

Special thanks to Helena Link for the workshop orgonisation and for correcting typos in this text.
